REPORT ON MAGNETIC SURVEY
ON
CODY 44
INTRODUCTION:
In September of 1979, a group of 42 claims were
staked to cover an area of Night Hawk Lake/ in the north half of Cody Township, and west of the main peninsula. A
further five claims were added in January of 1980 to cover the remaining open shoreline area on the west boundary of the group.
The claims are numbered as follows:
P-540038 - P-540049 inclusive
P-540261 - P-540276 inclusive
P-539979 - P-539986 inclusiveP-536831 - P-536836 inclusive
P-528670 - P-528674 inclusive
Total - 47 claims
LOCATION AND ACCESS:
Cody Township is located approximately 12 miles
east of Timmins along Highway 101.
- 2 -
Highway 101 East passes approximately one mile north of Cody Township with Highway 575 branching southward, down onto the Northern Peninsula of Night Hawk Lake. The Cody 44 group lies only 1000 feet to the west of this road access, with only five percent of the claims covering land and the remainder are all water claims.
Highway 575 however, is not open in the winter, and access is generally limited to travel by s'nowmachine.
GENERAL GEOLOGY:
The Night Hawk Lake area consists of Cody, Macklem, Carman and Thomas townships and it has played an important role in the development of the Porcupine Gold Camp, since early 1900.
The rocks underlying it are of Precambrian origin with the oldest rocks being mafic volcanics with some minor felsic flows in south-western Carman Township. These are overlain by a predominantly felsic volcanic sequence which grades into a tuffaceous and sedimentary rock sequence which is most prominent in Cody Township.
Another mafic sequence overlies this and in fact makes up the largest portion of the volcanic rocks in the area.
There is considerable faulting throughout the four townships and it appears that up to five main systems may exist.
- 3 -
The larger regional Destor-Porcupine fault, crosses
the northern part of Cody and Macklem townships and lies just
north of the Cody 44 group.
PREVIOUS WORK:
Relatively little work has been done on this part
icular area covered by Cody 44.
In 1965, Broulan Reef Mines conducted a mag survey
which essentially duplicated the lower three quarters of our
existing property. However, no follow up work or drilling
was conducted at that time.
It appears to be the only recorded geophysical survey
in this area.
SURVEY METHODS:
Line Cutting - North-south lines were established at 100 metre
intervals with 20 metre station spacings.
The lines were numbered from 9 E on the east boundary
of the group to 25 W on the west boundary.
Magnetics - A model G-816 Geometrics Total Field Magnetometer
was used in this survey.
- 4 -
This instrument provides a - l gamma resolution
over a complete range to a maximum of 100,000 gammas.
Readings are given as a digital readout and are
independent of temperature, humidity and battery conditions
Magnetic base stations were established at 100 m
intervals coinciding with baseline and picket line inter
sections. Readings were corrected for duirnal drift using
the closed loop method.
SURVEY RESULTS:
There are only two dominant anomalous linear features,
which were outlined in the magnetic survey of Cody 44.
A north north-west striking mag high and parallel mag
low cuts through the east half of the group. This anomaly is
attributed to a fault structure extending from approximately
940 S on Line O to Line 1000 W at 12 N.
At the northern extremity of this fault, it inter
sects a weak mag high striking west south-west to Line 180 W
at 200 metres north. At this point, there is an abrupt break
in the continuity of the anomaly. While no distinct off
setting continuation of this feature is apparent, it is
probably caused by diabase.
While a number of other local magnetic features
- 5 -
occur within the survey area, no reliable assumptions can
be made as to their causitive nature without further
supportive work.
The overall magnetic background is uniform through
out the property, which tends to re-affirm most geological
speculation that the property is underlain mainly by mafic
volcanics.
Previous overburden drilling however, indicates at
least two areas on the group indicate bedrock of a sedimentary
nature.
Very generally, these would be claims P-540264,
P-536833 and P-536834 in the northwest. The second area would
be in the south end of the property, bounded by the assumed
fault to the east on claim P-540047 and on the north by a
possible contact extending from the fault westward along the
700 metre south stations of the picket lines to claim P-540271,
The area below this appears to be underlain by sediments.
CONCLUSIONS AND RECOMMENDATIONS:\
The magnetic survey in itself yielded little useful
information in the way of providing information on the under
lying geological nature of the property.
Due to the short erratic winter season and typical
thin ice conditions on the Night Hawk Lake, overburden drill
ing had to be carried out prior to the availability of the
magnetic survey results.
- 6 -
Consequently a number of magnetic features which could have been determined by drilling, were in fact, missed by the original pattern of the holes.
Therefore, if there is sufficient interest and importance attached to this group as a potential area of gold exploration, then I would recommend a partial reinstatement of the grid in a future winter season, in order to conduct follow up overburden drilling to determine the nature of other unconfirmed magnetic features.
